6.1 Record-mute mode or head identification selection
TDA9605H
The state of the RM control signal on pin RMHID is don't care in the playback mode. I2C-bus control bits HAC2, HAC1 and HAC0 offer a wide selection of playback amplification to fit different head and head transformer specifications. The advised setting of the playback amplification realizes a level of 24 mV (RMS) for each carrier signal after the head amplifier to obtain a 17 dB overhead compared to the auto-normal level (hi-fi detection). However, performance is not critical and a different setting can be used if desired. The carrier level can be measured using the HF envelope output voltage on pin ENVOUT (bit EOS = 1). During standard operating mode the HF envelope signal is derived from the left channel carrier amplitude (1.3 or 1.4 MHz carrier) but the special test 10 of the test mode also enables the HF envelope output of the right channel carrier amplitude (1.7 or 1.8 MHz carrier). The advised carrier playback level of 24 mV (RMS) equals an HF envelope voltage of 3.3 V. The head amplifier output signal can be monitored directly by using test 8 of the test mode. Pin ENVOUT functions as the test output showing 6 dB attenuation compared to the actual head amplifier output level (see Section 14.4). Table 1 Selection of the head signal LEVEL ON PIN RMHID lower than 0.6 V or between 2.65 and 3.8 V between 1.0 and 2.35 V or higher than 4.3 V RECORD-MUTE MODE SELECTION OF HEAD SIGNAL pin PBIN2 (head 2) pin PBIN1 (head 1)
Pin RMHID allows input of two independent digital control signals for selecting the record-mute or head identification modes which are voltage coded. The RM control signal is selected via a 10 k resistor and the HID control signal is selected via a 18 k resistor. This set-up enables the two signals within the TDA9605H to be separated. The RM control signal is only in use during the record mode (bit AFM = 1); during the playback mode (bit AFM = 0) the RM signal is ignored. Pin RMHID should be connected to ground when the RM control signal is not used. The use of the RM control signal is optional since the same function is available via the I2C-bus control in the record-mute mode. However, accurate timing of recording start and stop may sometimes be difficult to realize via the I2C-bus control. In this event the RM control signal can be used instead. There is also the possibility to use the record-mute mode control line of the video head amplifier. 6.2 Hi-fi audio output level
When the application circuit is used in accordance with the application diagram, the standard FM deviation of 50 kHz equals a 1 kHz audio signal of -8 dBV line output level (bit LOH = 0). A different standard audio level can be selected by changing the external filter components of the noise reduction on pins EMPHL and EMPHR (see Section 14.3). The standard audio level changes proportionally to the impedance of the external de-emphasis filter. 6.3 Reference current
HID SIGNAL LOW HIGH
The external resistor connected to pin Iref defines the internal reference currents and determines the temperature stability of circuits adjusted by the auto-calibration function. 6.4 6.4.1 Head amplifier PLAYBACK MODE
6.4.2
The record-mute mode is selected by setting bit AFM = 1 and either setting bits DOC, SHH and DETH to logic 0 or switching the RM control signal to HIGH-level. During the record-mute mode no recording current is present on pin RECOUT (see Fig.6). The head amplifier status actually equals the playback mode, however, the second amplifier stage is disabled to minimize power consumption. The RM control signal on pin RMHID enables fast switching between the record and record-mute modes (see Table 2). If the I2C-bus control is set to the record mode, the use of record-mute mode control via pin RM allows for accurate timing of recording start and stop, independent of the I2C-bus control (see Section 6.1).
The playback mode is selected by setting bit AFM = 0. During the playback mode the input circuit on pins PBIN2 and PBIN1 is enabled (see Fig.6). Pin RECOUT is disabled and pin HMSW shows a low impedance to ground, so realizing an AC ground for the head circuit via the external capacitor connected between these pins. The head identification (HID) signal on pin RMHID selects between the head signals on pins PBIN2 or PBIN1. Head selection is defined as shown in Table 1.

RM SIGNAL LOW
The DC bias current on pin RECOUT is changed proportional to the selected recording current for optimizing the performance and minimizing the power consumption for each recording current selected. A Boucherot damping circuit is connected between pin HMSW and ground to prevent head current resonance peaking. A capacitor of 10 nF and a resistor of 470 are specified in Fig.14, but the component values are not critical. 6.4.4 HEAD AMPLIFIER POWER SUPPLY AND GROUND
HIGH 6.4.3
higher than 2.65 V record-mute mode RECORD MODE
The record mode is selected by setting bit AFM = 1 and setting bits DOC, SHH and DETH from logic 001 to 111 and switching the RM control signal to LOW-level. During the record mode actual recording is activated and the recording current is output on pin RECOUT (see Fig.6). Pins PBIN2 and PBIN1 form a connection to the 5 V head amplifier supply voltage (VCCH). Pin HMSW is internally connected to pin RECOUT and the external capacitor has no function in this mode. The desired carrier mix ratio is set via I2C-bus control bits DOC, SHH and DETH. A wide selection of recording currents is available to fit different head and head transformer specifications and are set via bits HAC2, HAC1, HAC0 and range bit HRL. The setting of the carrier mix ratio does not change the selected recording current.
The head amplifier is supplied via a separate 5 V supply (pin VCCH) and ground (pin GNDH). A capacitor of 100 nF should be placed close to the device between pins VCCH and GNDH for proper decoupling of the power supply. The head amplifier ground (pin GNDH) should be connected to the main ground (pin GND).

6.5 Automatic calibration
TDA9605H
The integrated auto-calibration system is activated by means of bit CALS of the power byte (see Fig.7). The auto-calibration system ensures hi-fi processing is well in accordance with the VHS hi-fi system standard by an automated adjustment of carrier frequencies, band-pass filters and noise reduction filters. Calibration is only needed after start-up of the video recorder. The calibration settings remain stable as long as the supply voltage (VCC) is present. Auto-calibration is only executed in the record-mute mode or record mode and no standby mode or test mode should be selected, i.e. auto-calibration requires the setting of bit AFM = 1, bit STBP = 0, bit STBA = 0 and bit TEST = 0. Auto-calibration is started after setting bit CALS = 1. Calibration is performed fully automatically, using the HID control signal as a time reference. Audio signals are not disturbed during the calibration process. Calibration of the oscillator frequencies is performed by measuring the number of oscillator cycles within one period when the HID control signal is at HIGH-level and comparing this result with an internal value stored in the Read Only Memory (ROM). Four different ROM values are available for NTSC or PAL (SECAM) system calibration of both the left and right channel carrier. In case of NTSC a special routine is active for the calibration of the right channel carrier which results in a
frequency difference between the left and right channel carrier near to 401.2 kHz. This value effectively reduces the crosstalk from hi-fi carriers to video colour signal as present during Extended Play (EP) tape speed. NTSC calibration uses a standard HID control signal of 29.97 Hz (pulse width =16.683 ms) where PAL calibration uses a standard HID control signal of 25 Hz (pulse width = 20 ms). After auto-calibration the maximum frequency error is 5 kHz assuming a time error of maximum of 5 s when the HID control signal is at HIGH-level. Jitter on the HID control signal should not exceed 1 s to realize EP optimization within 2 kHz for NTSC. In general, the crystal based HID control signal available in the video recorder can be used without modification. When the calibration of the oscillators is completed the band-pass filters are calibrated. The integrated weighting and FM de-emphasis filters of the noise reduction are calibrated at the same time. The total auto-calibration time needed is maximum 17 cycles of the HID control signal. Completion of the calibration is signalled by bit CALR =1 of the read byte. The calibration can also be monitored by means of the envelope output. For this purpose the voltage on pin ENVOUT is forced to >2.5 V during the calibration. The audio signal to the audio envelope function (level meter) should be muted (i.e. output select = mute).

Otherwise, the audio envelope output voltage may become >2.5 V which makes it impossible to detect the completion of the calibration on pin ENVOUT. Calibration relies upon the frequency accuracy of the HID control signal. The calibration result may be incorrect when the HID control signal is disturbed during a critical part of the calibration. An additional check is incorporated to detect such a situation by reading bit CALE during calibration. When bit CALE = 1, the calibration result is detected to be unreliable due to external causes. A new auto-calibration can be started by setting bit CALS = 0 followed by setting bit CALS = 1. Bit CALE always reads logic 1 when bit CALS is logic 0. The oscillators and band-pass filters can be switched between NTSC and PAL system frequencies after a calibration in NTSC or PAL mode without the need of additional calibration. Switching between these system modes is executed immediately and can be done in any operating mode. The frequency accuracy of system switching is 100 3 kHz for both carriers. To obtain the best possible frequency accuracy in the record mode it is good practice to recalibrate after system switching. 6.6 Power muting
TDA9605H
Switching off and on of the power supply voltage or using the built-in passive standby mode results in rising and dropping of the output DC voltages and causes strong disturbances on the output pins. The TDA9605H includes three integrated mute switches to block such disturbances so avoiding the need for an external mute circuit. Pop-free line and RF converter output signals are realized by connecting the integrated power mute switches behind the line and RFC output capacitors. Power muting is active when bit MUTE = 1 (see Fig.8). Power muting is automatically activated when VCC is switched on, because this situation is the Power-on reset default state. The integrated mute switches on pins MUTEC, MUTEL and MUTER are closed and form a low-impedance path to ground. Furthermore, the pins RFCOUT, LINEL and LINER are current limited to -1 mA to avoid excessive supply currents and to achieve good noise attenuation without the need for a series resistor between the output and mute pins. Pins DECL and DECR are also current limited for using the integrated power mute switches or for assisting external muting.

During power muting the internal output signal is also muted. After the output DC voltage has been established power muting can be de-activated by setting bit MUTE = 0. Now the mute switches are opened resulting in a high-impedance path of 100 k to ground. The output current limiting is not active. Power muting is also used in combination with the integrated passive standby mode (bit STBP = 1). During this mode the output circuits are switched off and the line, decoder and RF converter output voltages decrease to 0 V using a discharge current of 1 mA. Do not set power mute mode and change the passive standby mode at the same time. Power mute mode should be activated first, followed by switching on or off of the passive standby mode to avoid possible output glitches. It should be noted that the time needed for stabilizing the output DC voltage is proportional to the output capacitor value. A safe mute time is 200 ms using a 10 F capacitor (tmute = C x 20000 s). Power muting consumes approximately 4 mA additional supply current, so to obtain minimum power consumption the mute mode should be de-activated after use. Very good performance is achieved for power-up, power-down and passive standby mode switching. An auto-mute function is included which activates power muting when the supply voltage drops below 7 V. The performance of this auto-mute function depends upon the power voltage drop rate. The voltage drop rate should not exceed 1 V during 10 ms. The best performance independent of voltage drop rate is realized by activating the passive standby mode before switching off the power supply voltage (by setting bit MUTE = 1 and bit STBP = 1). 6.7 Envelope output
TDA9605H
Pin ENVOUT is an analog output for stereo audio level (e.g. level meter display) and for playback FM carrier level (e.g. auto-tracking). The functional diagram is given in Fig.9 and the timing diagram is shown in Fig.10. Only one ADC input is needed on the microcontroller for reading all the required information. During the playback mode the selection between audio level and carrier level information is realized by setting I2C-bus control bit EOS (see Table 3). The AF envelope output is defined by the signal selection made at the output select. During the record mode bit EOS offers the selection between the audio level of the output select or the audio level of the fixed hi-fi stereo signal. This is a helpful setting when the microcontroller uses the audio level information to adjust the hi-fi recording level (volume control). The HF envelope output signal is continuous and is derived from the left channel carrier. The HF envelope output exhibits a logarithmic characteristic (see Fig.11). In a standard application circuit only the left channel carrier level is required to support auto-tracking or manual tracking. However, test 10 of the special test mode allows for the right channel carrier level output instead for measurement purposes (see Section 14.4). The AF envelope output as a function of the output level is given in Fig.12. The AF envelope circuit uses time multiplexing for the left and right channel audio level. A peak-hold function and dynamic range compression (square root function) are included for easy read out. The peak-hold function and the left and right channel multiplexing are controlled by the HID control signal on pin RMHID (see Table 4).

6.9 Audio dubbing
TDA9605H
The TDA9605H includes unparalleled functionality supporting the audio dubbing function of hi-fi video recorders. Audio dubbing is a feature which enables the recording of new sound material on the linear audio track (i.e. normal sound) of an existing recording. The dub-mix mode is selected by setting bit IS2 = 1, bit IS1 = 0 and bit IS0 = 1. Audio dubbing can be used in two different ways: * Output mix * Input mix. 6.9.1 OUTPUT MIX
The circuit changes into a mixing desk when using the dub-mix mode of the input select function in combination with the volume setting of normal select. A new linear audio recording can be created by mixing together the new and the original sound. Continuous user control over amplitude and ratio mix of the auxiliary input signal (e.g. a microphone input) and the original hi-fi playback sound is possible using the left and right channel volume controls. This function is realized inside the IC by connecting the auxiliary input signal pair (pins AUXL and AUXR) to the left channel volume control and the hi-fi output signal pair to the right channel volume control. The settings of the output select function are used to arrange the hi-fi selection and the output signals in the dub-mix mode. However, some of these settings are overruled in the dub-mix mode. The normal signal is available on the line outputs for monitoring the dub-mix recording signals in the output select function modes mix-left, mix-right and mix-stereo. Mix-stereo of the output select function is generally used for audio dubbing. In combination with the volume setting of normal select, user control over amplitude and ratio is offered for the auxiliary and the hi-fi signal as follows: (14 x aux left + 14 x aux right) x volume left plus (14 x hi-fi left + 14 x hi-fi right) x volume right. The dub-mix mode is to be used in the (hi-fi) playback mode. In the record mode, a signal loop from output to input can be closed which may cause audio oscillation. The auto-normal switching is not active during the dub-mix mode. The hi-fi sound is muted when no hi-fi input signal is detected; bit AUTN is not affected.
A new additional recording is made on the linear audio track. In the playback mode, the new linear audio sound and the original hi-fi sound are combined. In this way the hi-fi stereo quality remains and the linear audio sound is partly used (e.g. for commentary only). However, there is no control over the original hi-fi sound. Mixing of the hi-fi and normal sound signals in the playback mode is supported by the output select function mix-left, mix-right and mix-stereo (bits OSN, OSR and OSL) and creates a new fixed output signal of 12 x hi-fi plus 1 x normal. 2 6.9.2 INPUT MIX
A new complete recording is made on the linear audio track (see Fig.4). In the playback mode, only the linear audio sound is used. In this way the hi-fi stereo quality is lost, but total freedom in defining the new sound material is an extra advantage. Furthermore, such recording is no longer restricted to playback on hi-fi video recorders (with an output mix option).

7 7.1 I2C-BUS PROTOCOL Addresses and data bytes
TDA9605H
Full control of the TDA9605H is accomplished via the 2-wire I2C-bus. Bus speeds up to 400 kbits/s can be used in accordance with the I2C-bus fast-mode specification. Seven data byte registers are available for programming the device (write mode) and one data byte register is available for reading data from the device (read mode). The registers are addressable via eight subaddresses. Automatic subaddress incrementing enables writing of successive data bytes in one transmission. During power-up, the data byte registers and auto-calibration registers are reset to a default state by the use of a Power-On Reset (POR) circuit. The reset signal is derived from an internally generated voltage supplied by VCC. Table 6 Addresses and POR state bits ADDRESS BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0

In that case automatic subaddress incrementing is disabled. 2. It is advised to keep the not-used write bits equal to the POR state to accommodate future compatibility. 3. You cannot rely upon the state of the not-used read bits because their state may change during development.

Bit AFM controls the main mode of the hi-fi processing and head amplifier. The function of other bits of the control byte and bit EOS of the output byte depends on the state of bit AFM.

When during the playback mode no FM carrier is detected from tape, the normal audio signal on pin LININ is automatically selected by the output select function. For this auto-normal mode: * The timing of the hi-fi carrier detection can be selected via bit DETH which defines the auto-normal release time: - Fast mode: hi-fi detection delay is 1 to 2 HID control signal periods (for NTSC: 33 to 66 ms; for PAL: 40 to 80 ms) - Slow mode: hi-fi detection delay is 7 to 8 HID control signal periods (for NTSC: 233 to 267 ms; for PAL: 280 to 320 ms). * The state of hi-fi detection and auto-normal can be monitored by I2C-bus control bit AUTN of the read byte. * In case automatic selection of the normal audio signal is not required the normal input level control can be set to mute (bits NIL3 to NIL0 of the select byte).

Bit NTSC selects between the NTSC and PAL (SECAM) system carrier frequencies for the CCO modulators or PLL demodulators and the band-pass filters. FM carrier frequencies of 1.3 and 1.7 MHz are used for the NTSC system where 1.4 and 1.8 MHz are used for the PAL system. Different code settings for the auto-calibration circuit assure proper calibration using the standard HID control signal frequency of 29.97 Hz for NTSC mode and 25 Hz for PAL mode. After auto-calibration is completed bit NTSC enables instant switching between the NTSC and PAL system. Table 12 System standard selection (bit NTSC) NTSC 0 1 Note 1. Power-on reset state.

7.4.5 HEAD AMPLIFIER PLAYBACK AMPLIFICATION
TDA9605H
Eight settings of playback amplification can be selected for the head amplifier. The amplification values are valid for the head signals from pins PBIN1 or PBIN2 to the internal node between the head amplifier and HF AGC circuit. The setting of the playback amplification results in a selection of the hi-fi detection level (auto-normal function). The hi-fi detection level indicated is the RMS value of the left channel carrier signal on pins PBIN1 and PBIN2. The signal at the internal node can be monitored for testing purposes via pin ENVOUT using test 8 of the test mode. It should be noted that the output level of test 8 shows 6 dB attenuation compared to the internal node level.

HEAD AMPLIFIER RECORD CURRENT
A total of twelve settings of the recording current can be selected for the head amplifier record output pin RECOUT. Bit HRL of the select byte selects between high and low current settings. The recording current is defined as the peak-to-peak value of the current of the record output signal which includes both the left and right carrier signal. The selected recording current is independent of the selected record mix ratio setting, but recording is disabled during the record-mute mode as defined by the bits DOC, SHH and DETH or the control signal on pin RMHID.

The select byte is used for decoder output select, record current range select and linear audio volume control. 7.5.1 DECODER OUTPUT SELECT
By setting bit DOS = 0 of the output byte, the decoder output signal on pins DECL and DECR is defined by the output select function. However, by setting bit DOS = 1 the decoder select function enables several independent signal selections controlled via bits DOS1 and DOS0. Via the decoder select function the input signals on pins TUNL and TUNR, pins EXT1L and EXT1R and pin SAP can be selected. The mute mode can also be selected.

The auto-normal function is activated when no hi-fi signal is found on tape in the playback mode. Except for the mute mode, all output select function modes will be overruled and changed to normal. Control of normal input level should be set to mute for muting the hi-fi sound. The state of the auto-normal function can be monitored by reading bit AUTN of the read byte.

The power byte is used for power-up settings and the standby control mode. 7.9.1 CALIBRATION START
Automatic frequency calibration by setting the hi-fi modem, the band-pass filter and the noise reduction is performed after a change of bit CALS from logic 0 to logic 1. The use of auto-calibration is only needed after power-up (Power-on reset) of the supply voltage (see Section 6.5). Table 28 Calibration start (bit CALS) CALS 0 1 Note 1. Power-on reset state. The output signal on pin ENVOUT or bit CALR (calibration ready) and bit CALE (calibration error) of the read byte can be monitored to check for completion of the calibration. 1999 Apr 14 28 MODE no calibration note 1 start calibration start of the automatic calibration cycle DESCRIPTION
The DC output level on pins LINEL, LINER, DECL and DECR can be changed by setting bit VCCS to maximize the output power when using a supply voltage of 12 V. The use of power muting (bit MUTE = 1) ensures disturbance free switching of the line output signal when setting bit VCCS after power-up.

TDA9605H
Several special tests can be selected for test, evaluation and measurement purposes. The selection of these tests is made by setting bit HRL and bits NIL3 to NIL0. See Section 14.4 for an overview of the test modes. Table 30 Test mode (bit TEST) TEST 0 1 Note 1.

Bit HPD offers a special setting intended for use with some of the built-in test modes and for support of particular applications that do not require use of the integrated head amplifier. By setting bit HPD = 1 the head amplifier playback circuit is disabled. This mode enables direct input signal to the HF AGC circuit via pin HMSW (AC coupled via a 10 nF capacitor).

Note 1. Power-on reset state. 7.9.6 POWER MUTING
Setting bit PORR = 1 ensures a reset of bit POR of the read byte to logic 0. In this way, a reading of logic 1 for bit POR always indicates the occurrence of an actual I2C-bus register Power-on reset and can not be caused accidentally by other I2C-bus control bits. Bit PORR has no control function but it is an unused bit, dedicated by name to change the I2C-bus register content from the Power-on reset state. Bit POR of the read byte is a logic AND function for checking all I2C-bus register bits. Bit POR will read logic 1 when the I2C-bus register content equals the Power-on reset default state and also when this state is set via the I2C-bus control. Since a setting of bit PORR = 1 differs from the Power-on reset default state, it forces a reset of bit POR to logic 0 independent of other bit settings. Table 31 Resetting of bit POR (bit PORR) PORR 0 1 Note 1. Power-on reset state. MODE no reset bit POR reset note 1 reset of bit POR (read byte) DESCRIPTION
The power mute function controls the mute switches on the line and RF converter outputs. The power mute mode is automatically activated via the Power-on reset function during power-up of the supply voltage. During power-down, the mute switches are activated automatically by means of the auto-mute circuit which is independent of the setting of bit MUTE. When setting bit MUTE = 1 the output current on pins RFCOUT, LINEL, LINER, DECL and DECR is limited to -1 mA for controlled power-up response and the selected output signal is muted (see Section 6.6). Table 33 Power mute (bit MUTE) MUTE 0 1 Note 1. Power-on reset state. MODE no mute mute DESCRIPTION power muting released: mute switches are open power muting activated: mute switches are closed; note 1

7.9.7 STANDBY SELECT 7.10.1 CALIBRATION READY
TDA9605H
The TDA9605H is switched in the low-power active standby mode by setting bit STBA = 1. Most circuits are switched inactive for reducing power consumption. However, the RF converter, line and decoder outputs remain active in this mode and the direct audio selections offered via the line select function and the decoder select function remain available. The selected output signal is muted during the active standby mode. The TDA9605H is switched in the minimum power passive standby mode by setting bit STBP = 1. All circuits are switched inactive to obtain minimum power consumption except for the power mute circuit, the I2C-bus and the line input reference buffer (i.e. the DC voltage on pins 1 to 11 remains active). When bit STBP = 1 a discharge current of 1 mA is active on pins RFCOUT, LINEL, LINER, DECL and DECR. Power muting ensures disturbance-free switching of the line and RF converter outputs to and from the passive standby mode. In the passive standby mode power muting can be de-activated again to achieve minimum power consumption. The calibration and I2C-bus registers are not affected in the active standby or passive standby mode. Table 34 Standby passive (bit STBP) and standby active (bit STBA); note 1 STBP 0 0 STBA 0 1 MODE operating active standby passive standby DESCRIPTION standard operating mode: full function; note 2 active standby mode: reduced power consumption passive standby mode: minimum power consumption
The completion of calibration is signalled by changing bit CALR from logic 0 to logic 1. Bit CALR remains logic 0 if for some reason a calibration can not be completed (i.e. no HID control signal available or the hi-fi processing is in the playback mode). Bit CALR will also return to logic 0 if calibration is lost due to a Power-on reset situation. Additional information about the calibration result is available via bit CALE. Calibration is found correct if bit CALR = 1 and bit CALE = 0. Pin ENVOUT can also be used to monitor calibration (see Section 6.5). Table 35 Calibration ready (bit CALR) CALR 0 1 Note 1. Power-on reset state. 7.10.2 AUTO-NORMAL SELECTION DESCRIPTION not calibrated; note 1 auto-calibration completed
The auto-normal function is activated when no hi-fi carrier input signal is detected in the playback mode. The auto-normal function overrules the settings of the output select function and selects normal sound (i.e. linear audio) instead of hi-fi. The state of the auto-normal function can be checked by reading bit AUTN. The auto-normal function and therefore bit AUTN is only valid in the playback mode. Bit AUTN is always logic 0 in the record mode. Table 36 Auto-normal (bit AUTN) AUTN 0 1 Note 1. Power-on reset state. DESCRIPTION hi-fi carrier available; audio FM signal is detected from tape in playback mode; note 1 normal sound selected instead of hi-fi carrier; no audio FM signal is detected from tape

7.10.3 CALIBRATION ERROR
TDA9605H
An unreliable calibration result is indicated when reading bit CALE = 1. The calibration result is not reliable when during calibration the control signal on pin RMHID is disturbed due to an external cause. Such a disturbance of the HID control signal is detected when reading bit CALE = 1. A new calibration should be started to ensure proper calibration. Calibration is found correct when bit CALR = 1 and bit CALE = 0. Table 37 Calibration error (bit CALE) CALE 0 1 Note 1. Power-on reset state. 7.10.4 POWER-ON RESET DESCRIPTION not calibrated or calibration result is found correct; note 1 calibration error encountered during calibration
Detecting the occurrence of a Power-on reset by reading bit POR requires a setting of bit PORR = 1 after power-up. Bit POR is forced to logic 0 only by setting bit PORR = 1, so this setting is independent of other I2C-bus bit settings. After calibration a Power-on reset occurrence is also indicated by bit CALR = 0, because calibration will be lost. Table 38 Power-on reset (bit POR) POR 0 1 Note 1. Power-on reset state. I2C-bus state I2C-bus bit state equals the Power-on reset state; note 1 DESCRIPTION bit state differs from the Power-on reset
An internal Power-on reset signal is generated at power-up or during a power voltage dip. The I2C-bus data bits and auto-calibration registers are reset to a pre-defined state. When reading bit POR = 1, it indicates that the internal data bits are found to be in the POR state due to an actual Power-on reset or the I2C-bus control settings.

This test can be used with a HIGH-level input signal by setting bit HPD = 1; test input signal applied to pin HMSW. 2. Auto-normal is activated (bit AUTN = 1) during the test, i.e. the playback audio signal is not available. 3. The output level on pin ENVOUT shows 6 dB attenuation compared to the internal signal of the head amplifier output. 4. This test connects internal signal lines between the noise reduction and (de-)modulator circuit. The signals found here are not compensated for temperature or tolerance spread and therefore level measurements are only relative. Absolute values are not an indication of the overall performance. Typical audio level of the test inputs and outputs is approximately -6.5 dBV for the standard -8 dBV line level and 50 kHz FM deviation. 5. The expander test requires the auto-normal function to be set inactive; i.e. an FM carrier signal should be available.

17 SOLDERING 17.1 Introduction to soldering surface mount packages
TDA9605H
If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 17.4 Manual soldering
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. 17.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 230 C. 17.3 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed.
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.

TDA9605H
REFLOW(1)
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
